I just think different arch could have different
meaning about __init and __init_memblock, but
if a function call another function with __init_memblock
annotation or has reference to variable with __initdata_memblock,
then we have better to give it __init_memblock annotation.

Thanks for point out this, then I know why I haven't get
compile warning.

My first motivation to propose this patch was I found below
two functions have different annotation which I think they
should have the same annotation:

int __init memblock_is_reserved(phys_addr_t addr)
return memblock_search(&memblock.reserved, addr) != -1;

int __init_memblock memblock_is_memory(phys_addr_t addr)
return memblock_search(&memblock.memory, addr) != -1;
